I think the area of the box shows volume, and the color/intensity shows the price change.
They use something like it (though maybe fancier) at:

I wanted to do something like this for non-financial data.

What type of chart? Uses Red and Green Boxes, etc
To Draw such graph. there is some algorithm that you need to follow.
its possible with java itself. you dont need any special software.
for algorithm in detail follow this site.

also there are some open source software which have implemented this already.

i use JtreeMap which is french, but very easy to read, and it makes graph from plain xml file. above link has some explanation about that.
